Sizing Guide

Need Help Choosing a Case Size?

Here at Vaer our goal is to build watches that can be worn everyday, in all conditions. A critical aspect of longterm wear is comfort and fit. Having a watch that is either too big, or too small can quickly disqualify it from a place in your daily rotation. If you're new to watch case sizing, below is a general overview of the sizes of our 5 core case designs.

If you'd like to read our comprehensive guide to case sizing click here.

Watches are measured by case diameter. This measurement does not include the crown or lugs.

1) 36mm - Smaller Wrists
2) 38mm - Small/Medium Wrists
3) 39mm - Medium Wrists
4) 40mm - Medium Wrists
5) 42mm - Medium/Large Wrists

With that in mind, we've created this case sizing guide to help you choose the watch that is ideal for your particular wrist shape and style preference.

Notes: All Vaer watches are shown on the same 7 inch (177mm) diameter wrist. This is approximately the median wrist size of an adult man. Watches are shown in size from smallest to largest.

Strap Sizing Guide

Need help choosing your straps?

One of the most rewarding aspects of owning a watch is the opportunity for customize your straps. In addition to adding a unique personality to your timepiece, changing your straps is a great way to increase a watches value and functionality. Here at Vaer, every watch we sell comes with your choice to 2x quick change straps.

In addition to a comfortable Primary Strap made for in-water functionality, we allow you to choose from a wide range of Secondary Straps to suit a variety of functions and styles.

Because different straps have different manufacturing costs your choice of Secondary Strap will be reflected in the watch's final retail cost. All strap options can also be purchased individually if you're interesting in buying a third, or fourth strap.

Note: All Vaer watch straps are sized for 20mm lugs and are cross compatible between models. Vaer bracelets are custom fitted and are NOT cross compatible.

Sizing and Fit

This watch is sized at 36mm in diameter, and measures 43mm from lug to lug, giving it a medium-sized presence on the wrist, and complementing most men's wrists. The 40mm case is our most popular size, and we recommend it for anyone with wrists in the 6.5 inch to 8.5-inch range, or especially if you're someone who likes a bit more presence on their wrist (compared to our ultra-compact 36mm watches).

Built for extended outdoor use, this watch has been designed to be slim, lightweight, and as comfortable as possible, while still maintaining 10ATM water resistance. The watch case measures 8.4mm in height and has a case weight of 46 grams. The entire case is also rounded and ergonomic so it can be worn comfortably during activities like surfing or mountain biking.

This watch comes in a range of interchangeable strap options, and they are designed to fit wrists ranging from 6.4" to 8.5" in diameter - though we do have specialty straps available for those with wrists outside of this range.

Inspired by the field watches worn by American soldiers during WW2, the S3 Calendar carries the design language and proportions of a vintage classic, with the durability features that make it the perfect daily-wearer.

Why we love it

The Vaer S3 Calendar Field Watch draws inspiration from the legendary A-11 field watch worn by U.S. soldiers in World War II, merging that timeless military design with the practicality of a modern calendar complication. We love it for its balance of heritage and functionality—delivering both a clean, vintage-inspired aesthetic and the convenience of tracking the date in everyday life. The 36mm case is the perfect size for versatility, offering the same ruggedness and legibility that made the original A-11 a battlefield staple. Built to endure harsh environments, the S3 features a scratch-resistant sapphire crystal, locking screwdown crown, and a guaranteed waterproof warranty, making it ready for any adventure—whether it’s a daily commute or a weekend out in the wilderness.

The Perfect Everyday Watch

What's the best outdoor watch we could make for under $200? That was the guiding question for our S-series. Are there cheaper alternatives out there? Sure. Do those cheaper options feature sapphire crystal, a locking crown, and a guaranteed waterproof warranty? Definitely not.

1. Ocean-Ready

Life is unpredictable. The perfect everyday watch needs to provide peace of mind in all conditions. Whether you're heading out in the rain or taking a jump in the pool, this watch never needs to be left on the sidelines.

2. Scratch Resistant

Impact is inevitable. When it happens, you want to be sure your watch won't scratch. That's why we use premium sapphire crystal to protect our dials (the second hardest material after diamond).

3. Easy Customization

Every day is different. And the easiest way to switch up the look (and functionality) of your watch is to change straps. That's why every Vaer watch ships with 2x quick-change strap options.

This watch is powered by a battery that will keep accurate time for 3-5 years. After this period, the battery can be easily replaced either by a local watch shop or by our team of technicians in Los Angeles.
